Mari Weiss is talkin' about sex, ba-by. Well, actually, she's a volunteer sex education teacher. You say potato, we say wear a condom. We're talking the good of teaching, specifically gender, anatomy, reproduction, and how someone who grew up Catholic in the '70s (her, not me) finds the connection with a post-millenial born audience. Fear not, this episode is still rated PG-13. We do giggle a lot, mostly at our collectively embarrassing pasts. Who's ready to get good and barely even dirty with us?
